Use of IP networks for digital audio transmission

This bachelor’s thesis explores the use of IP networks for digital audio transmission, focusing on their application in professional broadcasting environments. With the ongoing shift from traditional analog and point-to-point systems to more flexible and scalable options, Audio over IP technologies have gained significant relevance. This thesis presents an overview of digital audio fundamentals, IP networks, and key protocols such as Dante, AES67, and MADI. Particular emphasis is placed on synchronization through Precision Time Protocol (PTP) and the challenges of interoperability between different audio solutions. The practical section examines the implementation of AoIP in Czech Television’s mobile broadcasting unit DSNG46. Using three simplified network models and insights from four semi-structured interviews with engineers and crew members, the thesis analyzes how AoIP technologies influence workflow and production efficiency. Findings indicate that AoIP enables improved scalability, reduced cabling, and faster reconfiguration, making it suitable for mobile broadcast production. However, it also introduces challenges in terms of system complexity, increased demand for network expertise, and potential limitations in device compatibility. Despite these drawbacks, the benefits of AoIP are evident when proper planning, training, and infrastructure are in place. The thesis concludes that AoIP represents a forward-looking solution for modern broadcasting needs, particularly in mobile units, and highlights areas for further research and improvement.
